10:06 jiffin nbalacha: i will update the bug, I filed it long back(during my internship)
10:06 nbalacha jiffin, thanks

10:20 amarts ppai, kshlm, aravindavk who is working on shard volume type in gd2? i would like it to be separate volume type in 4.0 mainly because, once data is sharded, it can't be changed.
10:20 amarts atinm, ^^
10:21 atinm amarts, no one, we need to have a broader discussion and decision on this
10:21 atinm kdhananjay, ^^
10:21 atinm amarts, would you mind filing an github issue in GD2 and tag kdhananjay there?
10:22 atinm amarts, if shard continues to be a volume set option then there's no work required in GD2, but if its a volume type, then ofcourse we need some some work at GD2
10:26 kshlm Is shard an option to an existing xlator? Or is it an xlator?
10:26 amarts kshlm, it is a xlator, but is provided as an option for a volume
10:27 kshlm Ah, okay.
10:27 amarts but it is a such a special option, if set, we shouldn't be resetting it
10:27 amarts atinm, ack! will do
10:27 kshlm Doesn't make sense.
10:27 kshlm And as I understand, once shard is enabled, it cannot be disabled.
10:27 kshlm Right?
10:27 amarts kshlm, yes
10:28 kshlm And can shard be enabled on an in use volume?
10:28 apandey joined #gluster-dev
10:28 kshlm As in a volume having data.
10:28 kshlm I assume no.
10:29 kshlm If this is the case, it makes sense to have shard as a distinct volume type.
10:33 pranithk1 joined #gluster-dev
10:34 msvbhat joined #gluster-dev
10:34 amarts kshlm, it can be, but existing data will be lost (ie, on gluster mount point)
10:35 amarts so, for all practical purpose, it cant be set on existing volume
10:35 kshlm amarts, Yup. That's what I was getting at.
10:35 kshlm It can done now, because of how it was implemented.
10:35 kshlm But we can do it right with GD2.
10:36 kdhananjay kshlm: yes, it is allowed to enable sharding on an existing volume
10:36 kdhananjay kshlm: its just enough if we don't allow disabling of shard for now
10:37 amarts kdhananjay, do you have any reservation on keeping shard as new volume type?
10:37 kshlm kdhananjay, But if enabling shard means losing access to old data, then it shouldn't really be allowed, should it?
10:37 amarts shard replica, shard ec, ?
10:37 kdhananjay kshlm: thats not true. shard distinguishes between sharded and non sharded files by the presence of an xattr.
10:38 kdhananjay kshlm: access to pre-existing files will be handled by shard in terms of simply passing the requests down
10:38 kshlm I didn't know that. TIL.
10:39 kdhananjay amarts: not as long as non-sharded to sharded enablement is handled fine
10:39 kshlm Are there requests for allowing non-sharded to shard?
10:43 pranithk1 kdhananjay: ^^
10:44 kdhananjay kshlm: i didnt get you
10:44 skumar_ joined #gluster-dev
10:45 kshlm kdhananjay, Is anyone asking for the ability to convert a non-sharded volume to a sharded volume?
10:50 kdhananjay kshlm: i dont remember anyone asking about it. it's just that its allowed and it works. ;)
10:50 atinm kshlm, kdhananjay : but what people do ask is the other way around, isn't it?
10:51 atinm kdhananjay, but the question is having shard as a separate vol type, would that help us in achieving this requirement?
10:52 kdhananjay atinm: so having a separate voltype would mean the volume cant be converted between sharded <-> non-sharded?
10:54 atinm kdhananjay, ah right!
10:54 atinm kdhananjay, I was thinking it from a different perspective, sorry about the confusion
11:02 amarts people are asking it because we haven't clearly said what is the expectation.
11:03 amarts i think if we just say shard is another volume type, people won't ask for sharing the same volume... creating another volume is the answer

15:36 kkeithley anyone know anything about the warning that has appeared in rfc.sh recently?
15:37 kkeithley regex warning
15:37 kkeithley shyam: ^^^
15:38 shyam kkeithley: Huh! can you paste that? I did a submission yesterday and nothing popped up (or I did not notice it)
15:39 kkeithley Running coding guidelines check ...
15:39 kkeithley Unescaped left brace in regex is deprecated here (and will be fatal in Perl 5.30), passed through in regex; marked by <-- HERE in m/^(\+.*(?:do|\))){ <-- HERE / at ./build-aux/checkpatch.pl line 3102.
15:39 glusterbot kkeithley: <'s karma is now -16
15:39 glusterbot kkeithley: <'s karma is now -17
15:39 kkeithley on F27
15:41 shyam Oh, ok on F26 still (if that matters for this one). Can run a checkpatch separately anyway to check... in a call will check post that
15:51 susant left #gluster-dev
15:51 shyam kkeithley: I did not hit it on a patch that I tried (on F26, perl version v5.24.3), can you point me to your patch?

19:16 msvbhat joined #gluster-dev
19:46 kkeithley shyam: well, then it's a warning of things to come. Is the warning valid even if perl in f26 doesn't whine about it?
